Embodiments in accordance with the present invention provide for forming essentially pure diastereomers of 5/6-substituted norbornene-type monomers. Further, embodiments in accordance with the present invention encompass polymerizing such diastereomers to form addition or ROMP polymers where a desired exo-/endo-ratio of the diastereomers is provided to the polymerization, such ratio designed to provide a desired ratio of endo-/exo-structured repeating units for a resulting polymer to have desired physical or chemical properties.
根据本发明的实施例,提供形成基本纯的5/6-取代去氢莰烯型单体的异构体。此外,根据本发明的实施例涵盖聚合这种异构体以形成加成或ROMP聚合物,其中所提供给聚合反应的异构体的期望外/内比例设计为提供所得聚合物具有期望的物理或化学性质的外/内结构重复单元的期望比例。
